The bulb has 2 ports - the longer port is in the inlet - it connects up through the larger hole in the bottom of the tank and terminates at the fuel pickup assy inside the tank. The shorter bulb port is the outlet - it connects to the input of the carb (the bent port). The other port off the carb takes a smaller diameter tube back up to the tank - I guess this is the overflow line?
